Newly weaned pigs are susceptible to multiple stressors that may lead to postweaning diarrhea, thereby causing significant economic losses in the swine industry. Enterotoxigenic Escherichia coli strains are the major agents causing diarrhea in newly weaned pigs.

Resource efficiency, the ratio of inputs to outputs, is essential for both the economic and environmental performance of aquaculture. The data from commercial rainbow trout farms showed that from 1980 onwards, the farm-level feed conversion ratio (FCR) improved by 53.4%, and the specific nitrogen and phosphorus loading from the farms decreased by over 70%.

Treats are commonly given to dogs to create a better relationship with the owner. Most treats on the market are baked and wheat based as this grain has gluten that provides good texture attributes and facilitates production.

Canned wet foods are often blamed for poor oral health in dogs, but comparison between wet and dry foods is not commonly done. We used 12 healthy adult dogs to determine differences in oral health measures, breath odor, and oral bacteria populations of dogs consuming wet or dry foods.

Unlike human babies, calves do not receive protective immune proteins (immunoglobulins) from the mother before birth, so a sufficient volume of immunoglobulin-rich colostrum of adequate quality must be consumed within hours of birth. It can be a challenge to meet this requirement for all dairy calves.

Broiler chicken weight gain is a result of genetics and nutrition, with increased muscle mass attributed to accelerated embryonic myogenesis and posthatch muscle growth. During the avian incubation period, in ovo injection may be used as a strategy to deliver exogenous supplements into growing embryos for improving skeletal muscle development and growth.

Beta-adrenergic agonists (β-AAs) are supplemented to pigs and cattle to improve growth performance, carcass weight, and loin muscle area. Little is known about the mechanism taking place within individual cells by which β-AAs achieve this outcome.

The largest tissue in the body, skeletal muscle, is a heterogeneous mix of fibers that are categorized based on their primary source of energy production and speed of contraction. Evidence suggests that Thoroughbred horses with a greater percentage of type IIA, fast-twitch, oxidative fibers are more successful than those with fewer.

Heat stress (HS) and Zearalenone (ZEN), a toxic feed contaminant, affect growth, production efficiency, and animal welfare, and can cause death. As HS and ZEN independently increase oxidative stress, an imbalance of free radical production and clearance, and the likelihood of ZEN contamination during heat events, we hypothesized concomitant exposure would induce oxidative stress in pig skeletal muscle more than either agent alone.

One of the longest standing regional projects, the NC1184 group consists of 26 member agriculture experiment stations with a rich history of benchtop discovery in muscle biology with translation to the meat and livestock production sectors.

Skeletal muscle is a heterogenous population of cells that are classified into muscle types based on contractile speed and metabolism. The various types of muscle cells utilize different biochemical pathways to produce energy to support cellular functions.

Satellite cells are the resident stem cells found within skeletal muscle. Following strenuous exercise, the cells become mitotically active to supply progenitors for muscle repair. The signals responsible for their exit from the dormant state are largely unknown.

Turkey breast muscle growth and development are sensitive to temperatures immediately after hatch due to an immature thermoregulatory system. Meat yield or quality problems may arise from external thermal stress during this period.

Skeletal muscle growth is largely dependent on the proliferation and differentiation of muscle-specific stem cells known as satellite cells (SC). Previous work has shown that dietary inclusion of the vitamin D3 metabolite, 25-hydroxycholecalciferol (25OHD3), also called calcidiol, can promote skeletal muscle growth in post-hatch broiler chickens.

Heat stress reduces pig performance due to metabolic responses to heat. During heat stress, pigs lose the ability to metabolize fatty acids for energy and rely on carbohydrates to fuel growth.

Poor maternal diet during gestation results in changes in body composition and metabolism in the offspring. Here, we demonstrate that over- and restricted-feeding during gestation alter global protein expression in the longissimus dorsi muscle of offspring during gestation and just after birth.

Myoblasts are stems cells whose functional capacity can limit muscle growth. However, stressful intrauterine conditions cause these cells to be intrinsically dysfunctional. This restricts muscle growth capacity, leading to intrauterine growth restriction (IUGR) of the fetus, low birth weight, and less muscle mass after birth.

Mitochondria, colloquially referred to as the powerhouses of the cell, are essential for sustained energy production, which is particularly important for athletic performance. During exercise, reactive oxygen species (ROS) are produced as a normal byproduct of muscle contraction.

Among all the eating quality attributes of beef, tenderness is considered an essential factor influencing consumers’ overall satisfaction and future purchasing decisions. However, managing and predicting tenderness of meat products is challenging for the meat industry, as many factors can influence this attribute.

Two methods that the beef cattle industry can use to potentially improve efficiency, sustainability, and economic viability are growth promotants and crossbreeding cattle of different breed types. In the United States, over 90% of cattle receive at least one anabolic implant during the production cycle resulting in improvements in production and overall economic and environmental sustainability.
